CVE-2020-27658
CVE-2020-27658
In short
Synology Router Manager fails to protect its session cookie from being read by JavaScript code running in a browser. This allows attackers to steal the cookie and hijack user sessions.
Technical detail
The session cookie in SRM versions before 1.2.4-8081 lacks the HTTPOnly flag, enabling JavaScript-based XSS attacks to exfiltrate the cookie. Remote attackers can exploit this via malicious scripts to gain unauthorized session access, assuming the victim browses a compromised or attacker-controlled page while authenticated.
Summary generated and translated by AI from the official description.
Synology Router Manager (SRM) before 1.2.4-8081 does not include the HTTPOnly flag in a Set-Cookie header for the session cookie, which makes it easier for remote attackers to obtain potentially sensitive information via script access to this cookie.
